The Guardian Research Network: A Real-World Data Source for Pharmacoepidemiologic Research and Regulatory Applications.

Background: The quality of real-world data (RWD) directly impacts the value of real-world evidence (RWE) generated for regulatory decision-making. Data owners and investigators must be prepared to provide documentation on data quality assessments to regulators when submitting secondary data for regulatory purposes. While robust feasibility is required to justify the relevance of a data source for a specific research question, the reliability of the data, including the chain of custody and data journey prior to reaching the end user, is of equal importance for drawing valid, meaningful conclusions.

Virtual care in community pharmacy services: a scoping review.

Background: The integration of virtual care has been essential for maintaining continuity of patient care during and after the COVID-19 pandemic. Community pharmacists were among the healthcare professionals who used virtual care to provide remote pharmacy services. However, the use of virtual care in community pharmacy has not been comprehensively reviewed.

Long-Term Outcomes of 5-Fluorouracil-Related Early-Onset Toxicities: A Retrospective Cohort Study.

Objectives: We aimed to determine whether the occurrence of early-onset toxicities due to 5-fluorouracil (5-FU) in treatment-naive patients undergoing their first cycle of FOLFOX/FOLFIRINOX was associated with decreased overall survival, increased risk of treatment cessation, and hospitalization.

Methods: This was a retrospective cohort study using patient information from community oncology practices. Patients who received their first dose of 5-FU from 1 January 2015 through 1 August 2023 were included.

Protocol for a qualitative study exploring the pharmacist's role in supporting postsecondary students with psychotropic medication management.

Introduction: Findings from the National College Health Assessment (2019) stated that anxiety and depression are the most prevalent diagnosed mental illnesses among Canadian postsecondary students with one-fifth of students self-reporting a lifetime diagnosis. Psychotropic medications can be an important component of a multifaceted approach to the management and treatment of mental illness and are the most commonly dispensed via community pharmacies. Community pharmacies provide an opportunity for pharmacists to have a prominent role in supporting patients' psychotropic medication management.

Two "wild-type" variants of Escherichia coli sigma(70): context-dependent effects of the identity of amino acid 149.

The identity of amino acid 149 of Escherichia coli sigma(70) has been reported variably as either arginine or aspartic acid. We show that the behavior of both a region 1.2 deletion and a single-amino-acid substitution at position 122 are greatly affected by the identity of amino acid 149.
